FIELD OF THE INVENTION

The present disclosure relates to solid dosage forms comprising antiviral compounds, methods of preparing the solid dosage forms, and methods of using such dosage forms to treat antiviral infection.

BACKGROUND OF THE INVENTION

Hepatitis C virus (“HCV”) infection is associated with progressive liver pathology, including cirrhosis and hepatocellular carcinoma. Standard of care for treating chronic HCV infection generally comprises administration of peginterferon-alpha in combination with ribavirin to the patient. Treatment often additionally comprises administering a hepatitis C protease inhibitor to genotype 1-infected patients. Many patients, however, suffer side effects from the treatment, and viral elimination from the body is often inadequate. In view of the limited efficacy and tolerability of such standard of care treatment, there remains a need for new drugs to treat HCV infection.

II. SOLID DOSAGE FORMS

Combination therapy treatment of HCV-infected adult human subjects comprising the administration to those subjects of Compound 1, Compound 2, Compound 3, and Compound 4 (which are further described below) was evaluated in Phase III clinical trials. The Phase III trials employed two separate dosage forms, a first tablet comprising Compound 1, Compound 2, and Compound 3 (the “Triple Tablet”), and a second tablet comprising Compound 4 as the only active ingredient (the “Single Tablet”). The daily dosing regimen under evaluation in the Phase III clinical trials has required administration to the subject of two Triple Tablets and one Single Tablet in the morning and the administration of one Single Tablet to the subject in the evening. Initial results have indicated that such combination therapy treatment is effective.

A. Active Ingredients

Compound 1:

The compound (2R,6S,13aS,14aR,16aS,Z)—N-(cyclopropylsulfonyl)-6-(5-methylpyrazine-2-carboxamido)-5,16-dioxo-2-(phenanthridin-6-yloxy)-1,2,3,5,6,7,8,9,10,11,13a,14,14a,15,16,16a-hexadecahydrocyclopropa[e]pyrrolo[1,2-a][1,4]diazacyclopentadecine-14a-carboxamide (also known as ABT-450 or paritaprevir) is an HCV protease inhibitor and has the structure shown below:

For convenience, this compound and its pharmaceutically acceptable salts are collectively referred to as Compound 1 throughout this disclosure. The synthesis and formulation of Compound 1 are described, for example, in U.S. Patent Application Publication Nos. 2010/0144608 and 2011/0312973.

Compound 2:

The compound dimethyl (2S,2′S)-1,1′-((2S,2′S)-2,2′-(4,4′-((2S,5S)-1-(4-tert-butylphenyl)pyrrolidine-2,5-diyl)bis(4,1-phenylene))bis(azanediyl)bis-(oxomethylene)bis(pyrrolidine-2,1-diyl))bis(3-methyl-1-oxobutane-2,1-diyl)-dicarbamate (also known as ABT-267 or ombitasvir) is an HCV NS5A inhibitor and has the structure shown below:

For convenience, this compound and its pharmaceutically acceptable salts are collectively referred to as Compound 2 throughout this disclosure. The synthesis and formulation of Compound 2 are described, for example, in U.S. Patent Application Publication Nos. 2010/0317568 and 2012/0258909.

Compound 3: The compound 1,3-thiazol-5-ylmethyl N-[(2S,3S,5S)-3-hydroxy-5-[(2S)-3-methyl-2-{[methyl({[2-(propan-2-yl)-1,3-thiazol-4-yl]methyl})carbamoyl]-amino}butanamido]-1,6-diphenylhexan-2-yl]carbamate (also known as ritonavir) is a protease inhibitor and has the structure shown below:

For convenience, this compound and its pharmaceutically acceptable salts are collectively referred to as Compound 3 throughout this disclosure. The synthesis and formulation of Compound 3 are described, for example, in U.S. Pat. No. 5,541,206 and U.S. Pat. No. 8,268,349. Compound 3 is the active ingredient in the commercially available product NORVIR®.

Compound 4:

The compound N-(6-(3-tert-butyl-5-(2,4-dioxo-3,4-dihydropyrimidin-1(2H)-yl)-2-methoxyphenyl)naphthalen-2-yl)methanesulfonamide (also known as ABT-333 or dasabuvir) is a polymerase inhibitor and has the structure shown below:

For convenience, this compound and its pharmaceutically acceptable salts are collectively referred to as Compound 4 throughout this disclosure. The synthesis and formulation of Compound 4 are described, for example, in International Application Publication WO2009/039134.

Unless otherwise stated, any reference in this disclosure to an amount of Compound 1, Compound 2, Compound 3, or Compound 4 is intended to refer to the free acid or free base equivalent weight of the compound. For example, 350 mg of Compound 4 refers to 350 mg of the free acid of Compound 4 or an equivalent amount of a salt (e.g., a sodium salt) of Compound 4.

The present disclosure relates, in part, to one or more solid dosage forms that comprise all four of the active ingredients (Compound 1, Compound 2, Compound 3, and Compound 4) employed in the combination therapy evaluated in Phase III clinical trials discussed above. Such solid dosage forms, inter alia, can be administered to the subject pursuant to a once-daily dosing regimen, provide substantially comparable efficacy relative to, and are preferably bioequivalent to, the Triple Tablet/Single Tablet dosing regimen, and/or result in improved patient compliance. However, co-formulation of all four active ingredients in a single solid dosage form has been challenging in view of a number of factors, including the following:

(a) Total Daily Dose:

The combined daily dose of Compound 1 (150 mg), Compound 2 (25 mg), Compound 3 (100 mg), and Compound 4 (500 mg) administered to the subject in Phase III clinical trials is relatively large, totaling 775 mg and must be administered in four tablets.

(b) Dosage Form Size:

The Triple Tablet (1117 mg) and Single Tablet (697 mg) administered to subjects in Phase III clinical trials are large in size.

(c) Drug Loading:

Drug loading limitations previously impacted the development of the Triple Tablet. Consolidating the four active ingredients into a single dosage form only exacerbates that problem.

-   -   (d) Different Pharmacokinetic Profiles:

The daily dosing regimen for the Triple Tablet (once-daily dosing regimen) and the Single Tablet (twice-daily dosing regimen) differ, and deliver a specific pharmacokinetic profile for each of the four compounds.

-   -   (e) Solubility:

Compound 1, Compound 2, Compound 3, and Compound 4 have low solubility. They generally exhibit lower bioavailability and/or higher variability in bioavailability relative to more soluble compounds due to their poor aqueous solubility and low dissolution.

(f) Free Acid Conversion (Compound 4):

The free acid of Compound 4 exhibits good permeability but poor solubility in the gastrointestinal tract. Administering a salt of Compound 4 (such as the sodium salt) rather than the free acid form of Compound 4, however, does not improve Compound 4 solubility and uptake in the gastrointestinal tract to the extent expected due to unknown reasons.

(g) Regional Absorption (Compound 4):

The rate and extent of Compound 4 absorption varies throughout the gastrointestinal tract, making it difficult to design a once daily dosing that is bioequivalent to twice daily dosing.

Individually, the above considerations present significant challenges to co-formulating all four active ingredients in a suitable solid dosage form. Collectively, these considerations further increase the difficulty of co-formulating all four active ingredients in a suitable solid dosage form without adversely impacting dosage form size and/or the number of unit dosage forms that must be administered on a daily basis while achieving suitable efficacy and bioavailability.

B. Therapeutic Dose and Regimen

The dosage forms of the present invention are administered in accordance with a daily dosing regimen that orally delivers a therapeutic amount of Compounds 1, 2, 3, and 4 to a subject. This daily dosing regimen generally delivers an amount of Compounds 1, 2, 3, and 4 within the ranges set forth in Table A below.

TABLE A Daily Therapeutic Dose ACTIVE INGREDIENT DAILY THERAPEUTIC DOSE (mg) Compound 1 80 to 180 (e.g., 150) Compound 2 10 to 30 (e.g., 25) Compound 3 50 to 120 (e.g., 100) Compound 4 450 to 900 (e.g., 500 or 600) Due to drug loading limitations and dosage form size constraints, administration of two or more of the dosage forms of the present invention typically will be required to deliver the necessary daily therapeutic dose to the subject. In one aspect, daily administration of two of the dosage forms will provide the necessary daily therapeutic dose to the subject. In another aspect, daily administration of three of the dosage forms will provide the necessary daily therapeutic dose to the subject. If desired, however, daily administration of four or more of the dosage forms can be employed to provide the necessary daily therapeutic dose to the subject.

C. Dosage Form Illustrative Embodiments

-   -   (a) preparing a test solution comprising Compound 4, or a salt         thereof, and the stabilizing polymer, or combination of         stabilizing polymers;     -   (b) preparing a control solution, the control solution being         substantially identical to the test solution except that the         control solution does not contain the stabilizing polymer, or         combination of stabilizing polymers;     -   (c) maintaining the test mixture and the control solution under         the same conditions for a test period; and     -   (d) determining at the end of the test period the extent to         which precipitation of Compound 4, or a salt thereof, is         inhibited in the test solution relative to the control solution.

Suitable methods for determining whether precipitation of Compound 4 has been inhibited in the test solution relative to the control solution include UV/Vis spectrophotometry using an in situ UV/Vis probe; HPLC assay of the supernatant solution after removing particles; and other conventional methods known to those of skill in the art.

In one aspect, the stabilizing polymer, or combination of stabilizing polymers, inhibits precipitation of Compound 4 by at least 10% to 80% relative to a substantially identical dosage form that does not contain the stabilizing polymer, or combination of stabilizing polymers, as determined by the process comprising: (a) preparing a test solution comprising Compound 4, or a salt thereof, and the stabilizing polymer, or combination of stabilizing polymers; (b) preparing a control solution, the control solution being substantially identical to the test solution except that the control solution does not contain the stabilizing polymer, or combination of stabilizing polymers; (c) maintaining the test mixture and the control solution under the same conditions for a test period; and (d) determining at the end of the test period the extent to which precipitation of Compound 4, or a salt thereof, is inhibited in the test solution relative to the control solution by UV/Vis spectrophotometry using an in situ UV/Vis probe.

It is hypothesized that in dosage forms comprising a salt of Compound 4 but lacking a sufficient amount of the stabilizing polymer, or combination of stabilizing polymers, the salt is rapidly converted to the relatively insoluble free acid when the salt comes into contact with the acidic environment of the stomach. The free acid then precipitates on the surface of the solid dosage form without being released into the surrounding medium and/or precipitates out of the surrounding medium. This precipitation of the free acid results in a smaller amount of the administered dose of Compound 4 dissolving in the medium and being available for uptake and lowers the overall bioavailability of Compound 4. It is further hypothesized that the incorporation of the stabilizing polymer, or combination of stabilizing polymers, in the dosage form creates a microenvironment in the gastrointestinal tract in which the salt of Compound 4 dissolves to provide the free acid and the stabilizing polymer, or combination of stabilizing polymers, then functions to maintain the free acid in a supersaturated state in solution rather than precipitating out of solution. Because the amount of dissolved free acid increases and free acid precipitation is reduced, a larger amount of the administered dose is absorbed and the bioavailability of Compound 4 is increased.

As a result, the drug loading in a unit dose formulation comprising a salt of Compound 4 and a stabilizing polymer, or combination of stabilizing polymers, can be reduced without a reduction in Compound 4 bioavailability relative to a similar unit dose formulation having a higher drug loading but otherwise lacking a sufficient amount of the stabilizing polymer, or combination of stabilizing polymers. By facilitating a reduction in the required drug loading of the unit dosage form, the stabilizing polymer, or combination of stabilizing polymers, effectively facilitates a corresponding reduction in the size of the unit dosage form where desirable.

In general, the moisture content of the granulation mixture during fluid bed granulation is controlled to provide an acceptable level of adhesion between the Compound 4 particles and the copovidone particles. As the weight ratio of Compound 4 to total polymer in the granulation mixture increases (i.e., as the relative amount of Compound 4 present in the granulation mixture increases), the target moisture content selected for the granulation mixture during granulation typically will increase. In addition, it may be beneficial to maintain the granulation mixture in the fluid bed at the specified moisture content for an additional period of time (i.e., a “hold period”) to further facilitate additional growth, tighter particle size distribution, and/or improved mechanical properties of the granules. In one aspect, the granulation mixture comprises no more than 20 weight percent liquid during the granulation. In another aspect, the granulation mixture comprises no more than 14 weight percent liquid during the granulation. In another aspect, the granulation mixture comprises from 5 weight percent liquid to 20 weight percent liquid when the addition of the liquid to the granulation mixture has been completed (i.e., prior to drying the granulation mixture). In another aspect, the granulation mixture comprises from 8 weight percent liquid to 14 weight percent liquid when the addition of the liquid to the granulation mixture has been completed.

In each and every embodiment, example, preference and aspect described herein, at least a portion of the Compound 4 can be, for example, fluid bed granulated with (a) at least a portion of the pharmaceutically acceptable stabilizing polymer, or combination of pharmaceutically acceptable stabilizing polymers, and/or (b) at least a portion of the pharmaceutically acceptable release rate-modifying polymer, or combination of pharmaceutically acceptable stabilizing polymers, prior to blending with the other components of the formulation; and the weight ratio of Compound 4 (free acid equivalent weight) to total polymer (i.e., the combined weight of stabilizing polymer and release rate-modifying polymer) in the resulting granules is from 4:1 to 1:8.

In another aspect, the weight ratio is 6:1:4 (Compound 1:Compound 2:Compound 3).

In order to achieve the desired total drug loading, the first composition typically will comprise Compound 1, Compound 2, and Compound 3 in the form of an amorphous solid dispersion. In one embodiment, separate amorphous solid dispersions are prepared for each of Compound 1, Compound 2, and Compound 3 (e.g., individual mono-extrudates) and the separate amorphous solid dispersions are used to prepare the first composition. In another embodiment, a single amorphous solid dispersion comprising Compound 1, Compound 2, and Compound 3 (e.g., a co-extrudate) is prepared and used to prepare the first composition.

1. Individual Mono-Extrudates

In one embodiment of the present disclosure, each of the Compound 1, Compound 2, and Compound 3 components of the first composition is prepared as a separate amorphous solid dispersion comprising the active ingredient using hot melt extrusion technology and is milled prior to blending with the other two amorphous dispersions to form the first composition.

Additional information regarding the preparation of a Compound 1 mono-extrudate, a Compound 2 mono-extrudate, and a Compound 3 mono-extrudate can be found, for example, in published U.S. application US2011/0312973 and published international application WO2011/156578, both of which are incorporated by reference.

2. Co-Extrudate

In another embodiment of the present disclosure, Compound 1, Compound 2, and Compound 3 are prepared as a single amorphous solid dispersion comprising those three active ingredients using hot melt extrusion technology. The amorphous solid dispersion is milled and used to prepare the first composition.

Drug loads in conventional amorphous solid dispersions of poorly soluble compounds are generally no more than 15% by weight because higher drug loads can lead to a substantial reduction in drug release. Consequently, the Triple Tablet used in clinical trials was prepared from separate solid dispersions of Compound 1, Compound 2, and Compound 3, with each of the three solid dispersions having no more than 15% drug loading. As a result of the low drug loading, the Triple Tablet was relatively large in size.

Moreover, hot melt extrusion, a method commonly used to prepare amorphous solid dispersions, often involves the use of high temperature to assist the formation of a melt that is composed of all components of the final solid dispersion. Certain drug substances, such as Compound 3, can reach unacceptable degradation levels at temperatures of beyond 140° C., which considerably limits the use of the hot melt extrusion process to co-formulate Compound 3 with other drug substance(s) when the other drug substance(s) requires higher temperatures to form a suitable melt.

In contrast to conventional understanding, however, it has been found that Compound 1, Compound 2, and Compound 3 can be co-formulated in an amorphous solid dispersion having an increased total drug loading without compromising drug release. This allows the preparation of smaller solid dosage forms (e.g., tablets) comprising all three drug substances. In addition, when Compound 1, Compound 2, and Compound 3 were co-extruded in the hot melt extrusion process, Compound 3 became less susceptible to degradation at high temperatures. Even at a temperature of 165° C., Compound 3 degradation was well within the acceptable levels.

In another embodiment, the dosage form is an orally dispersible dosage form. The larger dosage form dimensions associated with a fixed dose combination product due to the higher-drug loading can present challenges (such as swallowing difficulties) for certain patients, especially pediatric and geriatric patients. As a result, patient compliance and use in pediatric patients may be limited. An orally dispersible dosage form (e.g., a dispersible dosage form that can disintegrate to fine dispersion within 30 seconds when in contact with water) can overcome such problems associated with dosage form size. Since the dispersible dosage form yields a fine dispersion upon immersion in water, the tablet dimensions should not impact patient compliance. In general, the dispersible dosage form can be prepared in any suitable manner including freeze-drying and direct compression methods. Excipients may include a pharmaceutically acceptable dispersing agent (such as lactose, glucose, cyclodextrin, sucrose, xylitol, mannitol, and sorbitol), a pharmaceutically acceptable disintegrant (such as croscarmellose sodium, cross-linked PVP, sodium starch glycolate, maize starch, carboxymethyl cellulose calcium, carboxymethyl cellulose sodium, and microcrystalline cellulose), and, optionally, a pharmaceutically acceptable lubricant (such as magnesium stearate, calcium stearate, aluminum stearate, stearic acid, sodium stearyl fumarate, talc, sodium benzoate, glyceryl mono fatty acid, glyceryl monostearate, glyceryl dibehenate, glyceryl palmito-stearic esters, polyethylene glycol, hydrogenated cotton seed oil, castor seed oil, and sucrose esters). The resulting blend can be incorporated into any suitable dosage form which facilitates the release of the active ingredients. Examples of such dosage forms include but are not limited to freeze-dried tablets, directly-compressed tablets, and lyophilized powders. The active ingredients can be provided, for example, in the form of individual mono-extrudates (Compounds 1, 2, and 3), co-extrudates (Compounds 1, 2, and 3), and mini-tablets.

VI. METHODS OF PREPARATION

The present disclosure also relates to methods for preparing the solid dosage forms described in this specification, including those methods described in the Examples below.

In one embodiment, the disclosure relates to methods for preparing a single amorphous solid dispersion comprising Compounds 1, 2 and 3 that can be used to in the preparation of the dosage form. The amorphous solid dispersion can be prepared by a variety of techniques such as, without limitation, melt-extrusion, spray-drying, co-precipitation, freeze drying, or other solvent evaporation techniques, with melt-extrusion and spray-drying being preferred.

In another embodiment, the method generally comprises, for example: (1) preparing a melt comprising Compound 1, Compound 2, Compound 3, a pharmaceutically acceptable hydrophilic polymer, and a pharmaceutically acceptable surfactant; and (2) solidifying the melt. The solidified melt can comprise any amorphous solid dispersion described or contemplated herein. The method can further comprise milling the solidified melt, followed by compressing the milled product with one or more other excipients or ingredients to form a tablet core. These other excipients or ingredients can include, for example, coloring agents, flavoring agents, lubricants or preservatives. In one aspect, the melt is formed at a temperature from 150° C. to 180° C. In another aspect, the melt is formed at a temperature from 150° C. to 170° C. In another aspect, the melt is formed at a temperature from 150° C. to 160° C. In another aspect, the melt is formed at a temperature from 160° C. to 170° C.

The melt-extrusion process typically comprises the steps of preparing a melt which includes the active ingredients (i.e., Compound 1, Compound 2, and Compound 3), the hydrophilic polymer(s) and optionally the surfactant(s), and then cooling the melt until it solidifies. “Melting” means a transition into a liquid or rubbery state in which it is possible for one component to get embedded, such as homogeneously embedded, in the other component or components. In many cases, the polymer component(s) will melt and the other components including the active ingredients and surfactant(s) will dissolve in the melt thereby forming a solution. Melting usually involves heating above the softening point of the polymer(s). The preparation of the melt can take place in a variety of ways. The mixing of the components can take place before, during or after the formation of the melt. For example, the components can be mixed first and then melted or be simultaneously mixed and melted. The melt can also be homogenized in order to disperse the active ingredients efficiently. In addition, it may be convenient first to melt the polymer(s) and then to mix in and homogenize the active ingredients. In one example, all materials except surfactant(s) are blended and fed into an extruder, while the surfactant(s) is molten externally and pumped in during extrusion.

In the melt-extrusion process, the active ingredients can be employed in their solid forms, such as their respective crystalline forms. The active ingredients can also be employed as a solution or dispersion in a suitable liquid solvent such as alcohols, aliphatic hydrocarbons, esters or, in some cases, liquid carbon dioxide. The solvent can be removed, e.g. evaporated, upon preparation of the melt.

Various additives can also be included in the melt, for example, flow regulators (e.g., colloidal silica), binders, lubricants, fillers, disintegrants, plasticizers, colorants, or stabilizers (e.g., antioxidants, light stabilizers, radical scavengers, and stabilizers against microbial attack).

The melting and/or mixing can take place in an apparatus customary for this purpose such as extruders or kneaders. Suitable extruders may include single screw extruders, intermeshing screw extruders or multi-screw extruders, such as twin screw extruders, which can be co-rotating or counter-rotating and, optionally, be equipped with kneading disks. It will be appreciated that the working temperatures will be determined by the kind of extruder or the kind of configuration within the extruder that is used. Friction and shearing of the material in the extruder may provide a substantial amount of energy to the mixture and aid in the formation of a homogeneous melt of the components. However, part of the energy needed to melt, mix and dissolve the components in the extruder can be provided by heating elements.

The consistency of the melt can range from thin to pasty to viscous. Shaping of the extrudate can be conveniently carried out by a calendar with two counter-rotating rollers with mutually matching depressions on their surface. The extrudate can be cooled and allowed to solidify. The extrudate can also be cut into pieces, either before solidification (hot-cut) or after solidification (cold-cut).

The solidified extrusion product can be further milled, ground or otherwise reduced to granules. The solidified extrudate, as well as each granule produced, comprises a solid dispersion, such as a solid solution, of the active ingredients in a matrix comprised of the hydrophilic polymer(s) and the pharmaceutically acceptable surfactant(s). The extrusion product can also be blended with other active ingredient(s) and/or additive(s) before being milled or ground into granules. The granules can be further processed into suitable solid oral dosage forms.

In one example, copovidone and one or more surfactants (e.g., vitamin E TPGS in combination with propylene glycol monolaurate) are mixed and granulated, followed by the addition of aerosil and Compound 1, Compound 2, and Compound 3. The mixture is milled, and then subjected to extrusion. The extrudate thus produced can be milled and sieved for further processing to make capsules or tablets. Surfactant(s) employed in this example can be added, for example, through liquid dosing during extrusion.

Alternatively, the amorphous solid dispersion can be prepared using the approach of solvent evaporation, via spray-drying, which provides the advantage of allowing for processing at lower temperatures, if needed, and also allows for other modifications to the process in order to further improve powder properties. The spray-dried powder can then be formulated further, if needed, and final drug product is flexible with regards to whether capsule, tablet or any other solid dosage form is desired.

Exemplary spray-drying processes and spray-drying equipment are described in K. Masters, SPRAY DRYING HANDBOOK (Halstead Press, New York, 4^(th) ed., 1985). Non-limiting examples of spray-drying devices that are suitable for the present invention include spray dryers manufactured by Niro Inc. or GEA Process Engineering Inc., Buchi Labortechnik AG, and Spray Drying Systems, Inc. A spray-drying process generally involves breaking up a liquid mixture into small droplets and rapidly removing solvent from the droplets in a container (spray drying apparatus) where there is a strong driving force for evaporation of solvent from the droplets. Atomization techniques include, for example, two-fluid or pressure nozzles, or rotary atomizers. The strong driving force for solvent evaporation can be provided, for example, by maintaining the partial pressure of solvent in the spray drying apparatus well below the vapor pressure of the solvent at the temperatures of the drying droplets. This may be accomplished by either (1) maintaining the pressure in the spray drying apparatus at a partial vacuum; (2) mixing the liquid droplets with a warm drying gas (e.g., heated nitrogen); or (3) both.

The temperature and flow rate of the drying gas, as well as the spray dryer design, can be selected so that the droplets are dry enough by the time they reach the wall of the apparatus to be essentially solid and to form a fine powder to avoid sticking to the apparatus wall. The spray-dried product can be collected by removing the material manually, pneumatically, mechanically or by other suitable means. The actual length of time to achieve the desired level of dryness depends on the size of the droplets, the formulation, and spray dryer operation. Following the solidification, the solid powder may stay in the spray drying chamber for additional time (e.g., 5 seconds to 60 seconds) to further evaporate solvent from the solid powder. The final solvent content in the solid dispersion as it exits the dryer is generally at a sufficiently low level so as to improve the stability of the final product. For instance, the residual solvent content of the spray-dried powder can be less than 2% by weight. The residual solvent content may be within the limits set forth in the International Conference on Harmonization (ICH) Guidelines. In addition, it may be useful to subject the spray-dried composition to further drying to lower the residual solvent to even lower levels. Methods to further lower solvent levels include, but are not limited to, fluid bed drying, infra-red drying, tumble drying, vacuum drying, and combinations of these and other suitable processes.

Like the solid extrudate described above, the spray dried product contains a solid dispersion, such as a solid solution, of the active ingredients in a matrix comprised of the hydrophilic polymer(s) and the pharmaceutically acceptable surfactant(s).

Before feeding into a spray dryer, the active ingredients, the hydrophilic polymer(s), as well as other excipients such as the pharmaceutically acceptable surfactant(s), can be dissolved in a solvent. Suitable solvents include, but are not limited to, alkanols (e.g., methanol, ethanol, 1-propanol, 2-propanol or mixtures thereof), acetone, acetone/water, alkanol/water mixtures (e.g., ethanol/water mixtures), or combinations thereof. The solution can also be preheated before being fed into the spray dryer.

The solid dispersion produced by melt-extrusion, spray-drying or other techniques can be prepared into any suitable solid oral dosage forms. In one embodiment, the solid dispersion prepared by melt-extrusion, spray-drying or other techniques (e.g., the extrudate or the spray-dried powder) can be compressed into tablets. The solid dispersion can be either directly compressed, or milled or ground into granules or powders before compression. Compression can be performed in a tablet press, such as in a steel die between two moving punches.

At least one additive selected from flow regulators, binders, lubricants, fillers, disintegrants, or plasticizers may be used in compressing the solid dispersion. These additives can be mixed with ground or milled solid dispersion before compacting. Disintegrants promote a rapid disintegration of the compact in the stomach and keeps the liberated granules separate from one another. Non-limiting examples of suitable disintegrants are cross-linked polymers such as cross-linked polyvinyl pyrrolidone, cross-linked sodium carboxymethylcellulose or sodium croscarmellose. Non-limiting examples of suitable fillers (also referred to as bulking agents) are lactose monohydrate, calcium hydrogenphosphate, microcrystalline cellulose (e.g., Avicell), silicates (such as silicium dioxide), magnesium oxide, talc, potato or corn starch, isomalt, or polyvinyl alcohol. Non-limiting examples of suitable flow regulators include highly dispersed silica (e.g., colloidal silica such as Aerosil), and animal or vegetable fats or waxes. Non-limiting examples of suitable lubricants include polyethylene glycol (e.g., having a molecular weight of from 1000 to 6000), magnesium and calcium stearates, sodium stearyl fumarate, and the like.

Various other additives or ingredients may also be used in preparing a solid composition of the present invention, for example dyes such as azo dyes, organic or inorganic pigments such as aluminium oxide or titanium dioxide, or dyes of natural origin; stabilizers such as antioxidants, light stabilizers, radical scavengers, stabilizers against microbial attack; or other active pharmaceutical ingredients.

D. First Bilayer Blend

A first bilayer blend comprising the Compound 1 mono-extrudate, the Compound 2 mono-extrudate, and the Compound 3 mono-extrudate was prepared. The mono-extrudates were each milled, combined in a 46:23:31 ratio (Compound 1:Compound 2:Compound 3) based on the weight percent of active ingredient, and blended with additional colloidal silicon dioxide to form the first bilayer blend having the composition reported in Table 1-E below.

E. Compound 4 Granules

Compound 4 was granulated with copovidone in a fluid bed granulation process. Compound 4 was added together with copovidone to the fluid bed granulator. The powders were fluidized with heated air at approximately 35° C. to 55° C. and water was subsequently sprayed from the top onto the fluidized powder bed. The water was sprayed at a rate sufficient to increase the moisture content of the granulation to a target of approximately 8% to 14% moisture. The water spray rate was then slightly reduced to maintain the granulation at the target moisture content for a hold period of approximately 15 minutes or longer. The spraying was subsequently stopped. The heated air temperature was increased and the granulation was dried until the moisture content was reduced to no greater than about 2 w/w %. The D₅₀ particle size distribution of the granules was between 80 and 130 microns. This method of granulation improved the bulk handling properties of the resulting combination of Compound 4 and copovidone while maintaining the intrinsic small particle size of Compound 4. The resulting Compound 4 granules had the composition reported in Table 1-F below.

The Compound 4 granules prepared as described above were then blended with HPMC Hypromellose 2208, colloidal silicon dioxide, and magnesium stearate to form the second bilayer blend used in the preparation of Formulation C5-12. The specific composition of the second bilayer blend is set forth in Table 1-G below.

F. Tablet Preparation (Formulation C5-12)

Formulation C5-12 was prepared by loading a unit dose of the second bilayer blend into the tablet die (oval, concave tooling, 10 mm width×18.8 mm length) on an automated bilayer tablet press, compressing the second bilayer blend with a compression force of approximately 4 kN, loading a unit dose of the first bilayer blend into the same tablet die on top of the previously compressed second bilayer blend, and compressing the first bilayer blend with a compression force of approximately 25 kN.

Example 2: Sink Conditions Dissolution Testing

The release profiles of Formulation C5-12 of Example 1 were evaluated in a Sink Conditions dissolution study. The study was conducted in 900 mL of dissolution medium using a standard USP dissolution Apparatus 2 (paddle) operating at 100 RPM at 37±0.5° C. The dissolution medium was a 0.05 M sodium phosphate buffer pH 6.8 with 15 mM cTAB as a surfactant.

Results for the Compound 1 component of Formulation C5-12 of Example 1 are reported in Table 2-A below.

Results for the Compound 2 component of Formulation C5-12 of Example 1 are reported in Table 2-B below.

Results for the Compound 3 component of Formulation C5-12 of Example 1 are reported in Table 2-C below.

Example 3: FeSSIF Dissolution Testing

Release profiles are obtained for Formulation C5-12 of Example 1 using a Fed-State Simulated Intestinal Fluid (“FeSSIF”) dissolution protocol under non-sink conditions. The study is conducted in 450 mL of dissolution medium using a standard USP dissolution Apparatus 2 (paddle) operating at 75 RPM at 37±0.5° C. The dissolution medium is a 0.04 M sodium phosphate buffer pH 6.8 with 11.2 g/L Phares SIF Original Powder (biorelevant.com, Croydon, Surrey, UK) to simulate FeSSIF conditions. Although the Sink Conditions dissolution method discussed in Example 2 provides results that are acceptable for general comparisons of release profiles, that method does not account for the conversion of a Compound 4 salt to the insoluble Compound 4 free acid in vivo and the resulting reduction in Compound 4 bioavailability that has been observed in vivo. The FeSSIF dissolution method provides results that more closely correlate with the observed in vivo results than the Sink Conditions dissolution method.

Example 4: Human Pharmacokinetic Study (Formulation C5-12)

A Phase 1, non-fasting, open-label, single-dose, two-arm, three-period, randomized, crossover study was conducted to evaluate the pharmacokinetics of Formulation C5-12 of Example 1 and several other formulations containing Compounds 1, 2, 3, and 4.

With respect to the observed pharmacokinetics of Formulation C5-12 relative to the reference regimen in Arm I of the study:

(1) C_(max) for Compound 1 was lower (by 30%) than C_(max) for the reference regimen. Otherwise, the exposures for Compound 1, Compound 2, Compound 3, and Compound 4 were comparable (less than 20% difference) to exposures from the reference regimen. Based on the exposures-efficacy of Compound 1, Compound 2, and Compound 3, however, these differences were not deemed clinically significant.

(2) For the AUC of Compound 4 and Compound 1 and the C_(max) of Compound 3, the lower 90% confidence bounds were slightly lower than 0.80 (less than 2% difference) and the geometric mean exposures were within 20% of the exposures from the reference regimen. These differences were not deemed clinically significant.

With respect to the observed pharmacokinetics of Formulation C5-12 relative to the reference regimen in Arm II of the study:

(1) Compound 1 and Compound 3 exposures (C_(24,ss) and AUC_(24,ss)) were bioequivalent (point estimate and 90% confidence interval for the geometric mean ratio (“GMR”) within 0.80-1.25) to exposures from the reference regimen except for C_(max,ss), which was lower (by 27% and 21%, respectively) than C_(max,ss) for the reference regimen. Based on the exposures-efficacy, however, the difference in C_(max,ss) was not deemed clinically significant.

(2) Compound 2 exposures were bioequivalent (point estimate and 90% confidence interval for the GMR within 0.80-1.25) to exposures from the reference regimen.

(3) Compound 4 exposures (C_(max,ss) and AUC_(24,ss)) were bioequivalent (point estimate and 90% confidence interval for the GMR within 0.80-1.25) to exposures from the reference regimen except for the C_(24,ss) (C_(trough)) which was lower (by 29%) than the C_(24,ss) (C_(trough)) for the reference regimen. Based on the exposures-efficacy, however, the difference in C_(trough) was not deemed clinically significant.
